Does anybody know the macros of minced chuck beef because each site writes down different data
It depends on the exact cut and grade of meat, as well as the amount of fat included.
If you don’t have any specific information about the meat that you purchased, I would probably just assume that it’s 80% lean, and that per 100g is it 250 calories, 17g protein, 0g carbs, 19.6g fat.
As far as ground beef, which is what I think you’re referring to here, it’s going to change depending on what you buy. It will say on the packaging what percentage fat it is and have the rest of the nutrition facts on the label just like any other food. Obviously, the lower the fat percentage, the higher the protein and the fewer the calories.
